1. An antenna system comprising, wherein the antenna system comprises
a bridge network comprising n bridge modules wherein a third port of a 1st bridge module in the n bridge modules is connected to a second port of an nth bridge module in the n bridge modules, a third port of an ith bridge module in the n bridge modules is connected to a second port of an (i−1)th bridge module in the n bridge modules; and
an antenna module comprising n antennas, wherein fourth ports of the n bridge modules are respectively connected to the n antennas, wherein i is an integer greater than or equal to 2 and less than or equal to n, and wherein n is an integer greater than or equal to 2;
wherein the 1st bridge module in the n bridge modules performs first weighting processing on a first analog signal input at a first port of the 1st bridge module and a second analog signal input at a second port of the 1st bridge module, to obtain a first component and a second component, and the 1st bridge module outputs the first component at a fourth port of the 1st bridge module, and inputs, at the third port of the 1st bridge module, the second component to the second port of the nth bridge module in the n bridge modules, to use the second component as a second analog signal of the second port of the nth bridge module; and
a kth bridge module in the n bridge modules performs first weighting processing on a first analog signal input at a first port of the kth bridge module and a second analog signal input at a second port of the kth bridge module, to obtain a first component and a second component, and the kth bridge module outputs the first component at a fourth port of the kth bridge module, and inputs, at a third port of the kth bridge module, the second component to a second port of a (k−1)th bridge module in the n bridge modules, to use the second component as a second analog signal of the second port of the (k−1)th bridge module, wherein k is an integer greater than 1 and less than or equal to n.
